I have a 2013 Juke Nismo that has just started making a strange ticking noise.. Essentially when warm if you rev it from idle it’s making a ticking noise however disappears during de-acceleration(revs dropping).. it’s present through all gears when accelerating and at idle. I have taken to 2 garages and they could not diagnose! It’s really annoying in the cabin hearing the noise, makes me hate driving my Nismo If anybody has the same or knows what it is please help
